Displacer Type Liquid Level Switches D E S C R I P T I O N Magnetrol® displacement type level switches offer the industrial user a wide choice of alarm and control configurations. Every unit utilizes a simple buoyancy principle and is well suited for simple or complex applications, such as foaming or surging liquids or agitated fluids, and usually costs less than other types of level switches. F E A T U R E S • Narrow or wide level ranges achieved through multiple switch mechanism capability. • Displacers adjustable at any point along the suspension cable. • 10 feet (3 meters) suspension cable standard • Anti-surge design eliminates the possibility of switch shortcycling • Flanged or threaded mounting available • Easy installation • Field adjustable set point and switch differential Displacer Level Switch Displacer Level Switch with PROOF-ER • NACE models • Floating rooftop models • Proof-er® ground check • Choice of displacers: Porcelain, 316 Stainless steel, Karbate, Brass. A P P L I C A T I O N S • Choice of switch mechanisms: Dry contact, Pneumatic, Hermetically sealed • Foaming or surging liquids • Available housings: NEMA 1, carbon steel for pneumatics; TYPE 4X/7/9, Class I, Div. 1, Groups C & D, polymer coated aluminum; TYPE 4X/7/9, Class I, Div. 1, Group B, polymer coated aluminum • Agitated fluids • Sewage handling • Dirty liquids • Paints • Varnishes • Heavy oils • Liquids with solids T E C H N O L O G Y Operation is based upon simple buoyancy, whereby a spring is loaded with weighted displacers which are heavier than the liquid. Immersion of the displacers in the liquid results in buoyancy force change, which moves the spring upward. Pivot 6 4 Return Spring 3 Since the spring moves only when the level moves on a displacer, spring movement is always a small fraction of the level travel between displacers . 5 A magnetic sleeve is connected to the spring and operates within a non-magnetic barrier tube . Spring movement causes the magnetic sleeve to attract a pivoted magnet , actuating a switch mechanism located outside the barrier tube. Built-in limit stops prevent over stroking of the spring, under level surge conditions. P R O O F - E R Rising Level 2 Falling Level C O N T R O L S The purpose of the PROOF-ER is to check the operation of a displacer control without having to raise the level in the tank. This is accomplished by pulling downward on the PROOF-ER chain. A spring-loaded lever arm then lifts F L O A T I N G 1 R O O F T O P The floating rooftop control is designed for installation on “barrier” (floating roof) tanks. The control will be furnished with a brass weight displacer to prevent sparking. the switch actuator simulating a high or high-high level condition. When the chain is released, the PROOF-ER returns the actuator to its previous position to resume normal operation. C O N T R O L S A hollow brass displacer is required if the control is to actuate in liquid as well as by the barrier. Consult factory for other options.

These instruments are factory calibrated to operate over a narrow level differential band and are ideally suited for liquid level alarm applications on either high or low level. The minimum differential band is approximately 6 in. (152 mm) in water and varies somewhat with liquid specific gravity. The maximum differential is determined by the length of the displacer suspension cable. The operating level is fully adjustable simply by repositioning the displacer along its suspension cable. The differential band varies slightly with liquid specific gravity.

These instruments utilize two switches — each actuated at a different level and each calibrated with a narrow differential band. OPERATING SEQUENCES Model B10 units are available with a choice of switch operating sequence. Five of the most popular sequences are described on page 8. When ordering, specify operating sequence number and specific gravity of the liquid.
